I'm using Zend Core for Oracle. I have a file called PTutil.php connects to oracle DB, query the DB and display results.

Currently I'm unable to make work due to this error:

PHP Fatal error:  Call to undefined method DB_Error::query() in ../Phonetimes/PTutil.php on line 192

The line 192 is this:

$res =& $db->query($query);

PEAR is installed and working fine.

I did some google search on this error, and tried what were suggested but still have the same error.

Can you please help me solve this error?

The error is basically due to the function query() being undefined. Why dont' you use straight off the oci8 methods. And then you can use oci_fetch_array() to fetch out any results you want, much like mysql functions.

$conn = oci_connect('scott', 'tiger', 'orcl');
$query = 'SELECT myclob FROM mytable WHERE mykey = :mykey';
$stid = oci_parse ($conn, $query);
oci_bind_by_name($stid, ":mykey", $mykey, 5);
oci_execute($stid, OCI_DEFAULT);

Open in new window

Thanks much nizsmo for the code.

Can you please explain to me what is mykey in this line:

oci_bind_by_name($stid, ":mykey", $mykey, 5);

I'm not sure why its needed.

I'm also getting this error:

Fatal error: Call to a member function fetchInto() on a non-object in /usr/local/Zend/apache2/htdocs/test.php on line 93

93:while ($res->fetchInto($row)) {

I'm really n00b in pear and connecting to oracle.

not too sure what fetchInto does? but have you set the $row variable?
You can fetch the results from the OCI connection using this function:

Also in case you are still wondering about the oci_bind_by_name() function:

Hope this helps!

Forgot to mention, in those sites above there are some nice examples, especially some full examples in oci_fetch_array() link, which will probably answer your questions :)
